POROUS CHARGE FOR CONTAINERS SERVING FOE STORAGE OF EXPLOSIVE GASES DISSOLVEI) III LIQUIDS, AS,

Ho Drawing.

T 0 all whom it may concern:

Be it known that I, EMIL Knnnnnr, a subject of the Republic of Germany, residing at Karlshorst, near Berlin, Germany, have invented certain new and useful Improvements in porous charge for containers serving for storage of explosive gases dissolved in liquids, as, for instance, acetylene (tor which application has been filed in Germany May 521, 1914i, Number 291,14Jl), of which the following is a specification.

The gas-containers tor acetylene which is dissolved in liquids, for instance acetone, have been filled up-to-now either with a stone-like mass or material of a grained or porous nature. The employment of highly homogeneous bodies entails the disadvantage, that t is impossible to undertake an inspection of the interior of the container or a test of the waterpressure to be repeated later on, without totally destroying the aforesaid bodies. If, on the other hand the charge consists of grained porous material as for instance, pumice-stone, silicious marl, charcoal or clay, the danger has been r ated that on account of the permanent shaking movement, for instance, when being transported, hollow spaces are formed within the charge, which constitute a dangerous actor in regard to the continuation of ex- Speeification of Letters Patent.

FOR INSTANCE, AGETYLENE.

plosions. It has already been suggested. to employ as charge a material such as charcoal.

In order to create a certain, interior pressure and elasticity within the charge, the admixture of naturally existing, porous, elastic materials as for instance, cork, elderpith, sponge or such like, which swell when the fluid for dissolving the acetylene is added, has proved quite sufficient. 40

If these porous materials capable of swelling are mixed with the known nonelastic, porous masses, and placed in the containers in a dry condition, an interior pressure will be created through the swelling of the component parts of the charge, when the dissolving fluid is admitted, which holds the dliferent parts of the charge together under increased friction, thereby preventing their displacement to each other and finally fills up any hollow spaces existing within the charge on account of their increase of volume.

Having fully described my invention, 1 claim:

A porous charge for acetylene gas containers, consisting of a mixture of crushed charcoal and cork.

In testimony whereof I atlix my signature.
